HEEL-PoLlsHlNe MACHINE.

SPECIFICATION forming part of Letters Patent No. 231,673, dated August 31, 1880.

' Application inea April 26,1880. (Model.)

To all whom it may concern:

Be it known that I, WILLIAM JoIN'r, of Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Heel-Polishing Machines, of

which the following is a specication.

My invention relates to improvements upon a heel-polishing machine issued to myselfand Geo. B. Dunham, ofdate 28th ofDecember,A. D. 1875, from the Patent Office of the United States, wherein two steam-pipes were incased in a hollow rocking shaft, and said pipes were provided with flexible joints and other devices outside of the rocking shaft, whereby steam constantly flowed through one of the said pipes into the hollow polishing-tool for the purpose of heating, and then was returned through the other pipe, and was expelled from the machine. In this invention the rocking shaft had to be drilled its entire length. Instead of this method of conveying steam to and ret-urning steam from the polishing tool, I have invented a shaft hollow in part, containing a single pipe incased within the hollow part, and the rest of said shaft is solid; and I have provided devices for conveying steam to and returning steam from the polishing-tool outside of the solid part of said rockin g shaft, thereby saving the expense of drilling. I have also a solid polishing-tool instead of the hollow polishingtool, thereby saving heat. And the object of the inventionis to produce abetter polishingtool and save expense in drilling the rocking shaft; and I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an elevation of the machine. Fig. 2 is a plan of the same. Fig. 3 is a horizontal section of Fig. l in line ac w. Fig. 4 is a vertical section of the polishing-tool and part of the pipes in line y y,- and Fig. 5 is a horizontal section of a modilcation of the pin holding the arm and polishing-tool together.

The letter Arepresents the standard or column; B, the jack, C, the heel; D,.thesolid polishing-tool; E, the tool-arm attached to a rocking shaft, F, said arm carrying at its other extremity the tool D; A' A', arms of the standard A, bearing the rocking shaft F 5 G, hollow steam -cylinder, containing in its hollow a steam-pipe, G'. H and H' are blocks having ing an orifice in the same; c', an opening into the sleeve, and c" a vent in said hollow shaft 5 al and d', nuts upon the pipes'I I'; c, a setscrew holding the arm E to the shaft F;

f, a pin holding the tool-arm and tool to-A gether, g, a set-screw bearing through one of the arms of'thejack against the heel 5 h, steampassage in head of polishing-tool; lc, the modication of the pin f,- land l', pipes attached to said modified pin 5 m, channel from one pipe into the other; a, washer upon shaft F, next to arm A, ando is a nut turning upon a screw, 0'. 1? is a coupling, which is screwed at one end to the end of the hollow shaft G, and the other end receives a pipe which inlets the steam used for heating the polishing-tool; a; x, horizontal section of a part of the hollow shaft, and y y vertical sectionpf pipes a. and a', the polishing-tool and pin. v

I will now show in what manner the steam is introduced and made to heat the polishingtool, and then is educted from the same, and wherein my invention in this respect differs from my former invention. The horizontal section of the hollow shaft G and the pipe G', the sleeve c, and coupling P is clearly seen in Fig. 3, which is a section of Fig. 1 in line w m. The sleeve c and coupling P, of course, are packed steam tight, and through this coupling P (shown in said Fig. 3) the steam flows in, and goesI through the tube G in a steam-channel through the blocks H and H' (see Figs. l, 2, 3) into the bent pipe or conductor I, (see Fig.2,) through the pipe a, exible joint b, pipe a, to the head of the polishing-tool D, heating' the polisher. It then flows through the steam-passage in the polishing-tool, (see Fig. 4,) and thence out through pipe a', joint b',"fpipe a', bent pipegor conductor I', through a steam-channel in said block H' and H, into the hollow shaft G, (see Fig. 3,) and makes its escape through the vent c" and opening c', and drips or is carried by pipe or other device to any convenient receptacle.

In my former patent the rockin g shaft is in one piece, drilled its entire length, and theinlet and outlet pipes are incased Within this shaft, and the conduction-pipes and exible 5 joints inlet to and educt from the polisher thev steam through these pipes.

In my present invention it will be seen that the drilling of the shaft is dispensed With, except in part, and' that the steam is carried to and returned from the polisher outside of the shaft F, thereby saving the expense of drilling. I also employ an arm, E, which, sliding on the shaft F, carries the polisher.

It Will be seen, also, that the polisher is solid, save the steam-passage shown in Fig. 4. The advantage of a solid polisher is, that when once heated it is less liable to cool and will continue heated with less application ofsteam, and cannot burst.

Figs. l and 4 show that the solid pin f goes through the neck of the polisher from side to side. Instead ot' a pin of this construction, I suggest that a modification thereof may be made, as shown by Fig. 5,'Wherein a pipe, Z, (same as pipe a, Fig. 2,) enters the passage m, and steam flows into and through the passage m and out through the pipe l', (same as pipe a, Fig. 2.) The modified pin is simply a double joint, such as are seen in gas-fixtures, and a polisher may be heated by this device instead ot the above-described method.

What Iclaim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for polishing the heels of boots and shoes, the combination of the hollow shaftG, provided with a vent therein, c, the pipe G', the blocks H and H', provided with steam-passages in them, the conductors I and I', the pipes a at ct' a', the flexible joints b and b', the solid polisher D, having a steam-passage, t, therein, the sleeve c, provided with an opening, c', whereby a current ot' steam is made to ow into and heat the solid polisher D and escape therefrom, substantially in the Ina-nner and for the purpose shown and described.

2. The combination of the oscillating shaft F, the sliding arm E, and the described polishing-tool D, the same being connected by a 'pin,f, which allows a rocking motion of the polisher upon the heel, substantially in the manner and for the purpose shown and described.
